Are you using the latest version of the driver? We used to have some
problems with mpeg1 sync in the past, but hoped that we got rid of
them. 
If you are using VCD files you have to make sure that you used a
program like vcdrip to get the mpeg file from the vcd, otherwise you
won't get correct playback.
You can also try remuxing with the mplex program set to MPEG1, but
that shouldn't be necessary.
